TO WHOM IT MAY CONGERN:

Be it known that I, DAVID CAMMERER, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improved Beer-Cooler; and I hereby declare the following to be a fnll,-clear, and exact description.

thereof, reference being had to the accompanying drawings, making part of this specification.

This is an improvement on that class of refrigerating-apparatus in which the wort or other liquor is cooled by-being made to dribble or trickle over the outside of a conduit or receptacle of ice-water, orother refrigerant; and my invention consists in certain' forms and constructions of thcwater-containing and beer-distributing devices, which combine the advantages of a high degree of eiciency with simplicity and economy.

Figure 1 is a perspective view of a beer-cooler embodying my invention.

Figure 2 is a transverse section.

Figure 3 is a horizontal section on the line 2z: x, iig. 1.

A is a cold-water-supply pipe, entering the bottom of a refrigerator of the following construction:

B B' are two sheets ot copper, placed in a vertical position, and havingtheir top-and bottom edges securely fastened together, their intermediate portions being crimped or corrugated, so as to a'ord a series of cylindroidal zhambers, C1 C2 C3 C* C5 C, that communicate with each other by means of narrow passages, Dl Dz I)3 D4 D, which have vertical corrugations, d, and are secured at the proper distances apart by means ofvbloeks or Washl ers, E, and rivets F.

The upper and united edges of the sheets B B' form' an elevated ridge, G, which supports `a duplicated distributing-trough, H H', having several ranges of ori'dces, hi h' h3, on each side, adjacent to the said ridge G.

Sloping plates or vflanges I I', with orifices z', serve the double, purpose of holding the distributing-trough, L and of conducting and distributing the liquor to tbc cooler. Resting upon the trough is a. ciillender, K, whose perforated bottom, k, while allowing the descent of the liquor, retains any hops or other fragments that maybe floating therein.

Spouts L L', from the opposite ends of the upper chamber C, conduct off the spent or heated water.

Screw-caps M afford access to the chambers, for the insertion of ice, cleaning, de.

A' cock, N, from the bottom chamber, enables the emptying of the refrigerator, when desired.

O is a pan or trough for cat-ching, and P-a spout for conducting oli` the cooled wort.

In comparison with thc customary stack of horizontal pipes, connected at alternate ends, my present improvement is n ot only much cheaper of construction, but is far more edicient. I

The narrow slit or ventage, along the top of each chamber, allows of the free ascent of the more heated l portions of water, which, in the common form, become entangled in the cireuitous convolutions of the pipes.

l The natural tendency of fluids to seek a Icentral chamber will be compensated for by a precisely corresponding action of thewarm and cold currents. l Y l y I amr aware that a'patent was granted, July 16, 1861, to George B. Turrell, for a beer-cooler, formed oi metallic plates, between whichvthe cooling-liquidA is passed. This, therefore, I do not claim.

I claim herein as new, and of my inventionl The combination of the two supporting-flanges I I, pert'oratedat iz', the elevated ridge G, the double trough 'H H', perforated at h h', and the vertically-corrugated hollow webs Dl D', affording water-communication throughout the length of the chambers Cf C2, or nearly so, the whole being arranged as and for the purposes set forth.

In testimony of which invention, I hereunto set my hand:

DAVIDy GAMMERER.
